PAUL COLE, OF TYRRELL, OHIO.

DEVICE FOR MANIPULATING JAR-CLOSURES.

To all whom it may concern:

Be it known that I, PAUL COLE, citizen of the United States, residing at Tyrrell, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Devices for Manipulating J ar- Closures, of which the following is a specification.

This invention relates to an attachment for jar closures, and has for an object to provide a device adapted to assist in placing closures tightly on jars, and to assist in removing the closures from the jars when they cannot be removed by hand.

Another object of this invention is to form an attachment of this character especially adapted to the Mason jar and to provide a supporting member adapted to engage with the jar, to provide a gripping member adapted to engage with the closure, and to provide a hand operating lever having connection to both the supporting member and the gripping member to rock the latter with respect to the supporting member for turning the closure to release the same therefrom.

The invention further contemplates the provision of a device of this character which is comparatively light in weight and simple in construction so that it can be readily handled and carried, and one which may be economically produced.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a perspective view of the improved device as applied to the jar; Fig. 2 is a vertical sectional view through the same; Fig. 3 is a top plan view of the supporting member, partly in section; Fig. 4 is a detail bottom plan View of the outer jaw; and, Fig. 5 is a detail perspective View of the adjustable connection employed with the supporting member.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the same reference characters.

Referring to the drawing the numeral 10 designates a jar of the common type which is provided with a slightly reduced and threaded neck 11 over which engages a threaded closure or cap 12.

The improved attachment comprises a cir- Specification of Letters Patent.

cular metallic band 13 forming the supporting member which is provided with an inner lining 14 of rubber, leather, or the like, and which is formed at one of its ends with a plurality of outwardly extending ears 15 employed in holding the band in position. The ears 15 are preferably stamped from the body of the band 13 and are disposed in longitudinal alinement upon the hand. The opposite end of the band 13 carries a hinged hook 16 formed of a metallic casting having its returned or hooked portion hinged at its extremity upon a pintle 17 carried in the overturned end of the band 13. A spring 18, in the form of a link, the opposite sides thereof being helical springs while the ends of the spring 18 are formed into loops engaging respectively over one of the ears 15 and upon the hinged hook 16. The stop 19 projects inwardly from the long arm of the hook 16 to prevent the displacement of the spring 18 when the hook 16 is swung outwardly about the pintle 17 to enlarge the band 13. Midway of the ends of the band 13 a socket 20 is pivotally mounted, the same comprising a strip of metal bent into U-form and having its closed end seated against the outer side of the band 13 and held rotatably by a rivet 21. The outwardly extending arms of the socket 20 are provided with vertically registering openings.

In conjunction with the above described supporting member, a gripping member is employed which is in the form of a link 22 adapted to engage over the upper side of the closure or cap 12. An outer jaw 23 is hinged at its central portion upon the outer end of the link 22, the jaw 23 comprising an arcuate casting conforming substantially to the curvature of the cap and fitting against one side of the same. The inner edge of the jaw 23 is formed with a plurality of teeth 24: adapted to engage against the cap and hold the same from rotation with respect to the jaw. The jaw 23 is of arcuate form and is of such size as to engage substantially halfway around the closure 12. A short inner jaw 25 is hinged midway of its ends upon the link 22 adjacent to its inner end and is adapted to bind against the closure 12 at a point substantially opposite to the outer jaw 23. From Fig. 2 it will be noted that the jaws 23 and 25 are formed with slightly rounded gripping edges, as at 26, and that the jaws are provided with overhanging and inwardly extending flanges 27 through which the rivets 28 pass fastening the jaws to the link 22. The jaws 23 and 25 are loosely hinged upon the link 23 so as to admit the adjusting of the same to the closure 12.

The pivoted socket 20 carries the lower reduced end of the rocker arm 29 which extends upwardly therefrom, being enlarged at its central portion, and is reduced at its upper end to fit loosely through an opening 30 formed in the inner extremity of the link 22. The link 22 is of such length that its outer end registers vertically over the pivoted socket 20. The rocker arm 29 forms an inner T-head upon a hand lever 31 which projects outwardly from the rocker arm 29 and is adapted to be grasped by the hand and moved up and down to rock the arm 29. The opposite extremities of the rocker arm 29 are headed, as at 32, the upper head being spaced slightly above the link 22 to admit of the free play of the rocker arm through the link during the reciprocating action of the gripping member.

In the operation of the device, the supporting member is engaged about the jar body 10 below the neck 11, the spring 18 being adjusted to engage over one of the ears 15 to bind the band 13 tight about the jar 10 when the hinged hook 16 is swung against the outer face of the band. The jaws 23 and 25 are engaged against the opposite sides of the closure 12. \Vhen the hand lever 31 is moved down the upper end of the rocker arm 29 is drawn forwardly and rotates the link 21 upon the jaw 23 to bind the inner jaw 25 against the opposite side of the closure 12 and effect the turning of the closure. When the hand lever 31 has reached the limit of its downward movement it is raised to release the inner jaw 25 from the closure 12 and to carry the same back to its normal position. The outer jaw 23 is then loose against the closure and can be i moved by hand into a new position when the handle 21 is again depressed to move the closure about the neck 11. The swinging movement of the rocker arm 29 turns the socket 20, and usually one depression of the lever 31 is sufiicient to loosen the closure 12 upon the neck 11. In a like manner the closure 12 may be tightened by simply reversing the position of the inner jaw 25 and swinging the hand lever 31 to the opposite side of the link 22.

Having thus described the invention, what is claimed is:

1. A device for manipulating jar closures comprising a supporting member for engagement about a jar, a gripping member adapted to bind upon the jar closure, and a hand lever pivotally connected at its inner end to the supporting member and to the gripping member for turning the latter with respect to the supporting member. 7

2. A device for manipulating jar closures comprising a supporting member for binding engagement about the body of a jar, a gripping member adapted to bind over a jar closure, and a rocking arm connecting the supporting member and the gripping member for turning the latter with respect to the former.

3. A device for manipulating jar closures including a supporting member carried upon the jar, a gripping member engaging with the jar closure, a lever disposed between the supporting and the gripping members and having an inner T-head pivotally connected at its ends to the members for moving the same past one another.

1. A device for manipulating ar closures including a band for detachable engagement about a jar, a rocker arm pivoted at one side of the band and extending up therefrom, a link loosely connected to the upper end of the rocker arm and extending across the jar closure, binding jaws carried in spaced and pivoted relation upon the link for engagement against the sides of the closure, and a handlever disposed upon the rocker arm for moving the same. i

5. A device for manipulating ar closures including a band encircling the body of the jar, a yielding lining carried by the band for engagement against the jar, a spring loop adjustably engaging across the free ends of the band to hold the same from rotation upon the jar, a pivoted socket carried upon one side of the band, a rocker arm carried in the socket and extending up therefrom, and a gripping member loosely connected to the upper end of the rocker arm and engaging with the closure of the jar.

6. A device for manipulating a cylindrical jar having a rounded closure comprising a supporting member detachably engaging about the jar below the closure, a gripping member binding adj ustably about the round ed outer face of the closure, and operating means connecting the members for moving the gripping member.

In testimony whereof, I aflix my signature in presence of two witnesses.
